Why can't I create a Disk Group for a specific disk in PERC 6?

  • 772

I have a Dell PowerEdge 1950 server with a PERC 6 RAID Controller that needed some attention yesterday due to vmware ESXi first telling me it lost connection to one disk, then logging it lost connection to all four disks finally gaining connectivity back to 2-3 (can't remember exactly) of the disks. I tried to remount the old disks, but it didn't work so I restarted the machine. Of course it got stuck with BIOS error prompt on boot until I could physically check the server.

Debugging this it turns out that the BIOS RAID discovers all four disks (they are all listen in PERC). However, when I try to create a Disk Group I can't select the disk in Slot 1. I know this is independent of which disk I put in slot 1.

Have anyone experienced anything similar before? What could it be?

Additional information:

  • No errors are presented whatsoever.
  • All four disks are not reporting any errors.
  • No Foreign Configuration is present.
  • I have tried resetting the Controller Configuration. Still disk in Slot 1 is not selectable.
  • Every disk group I am trying to create is RAID 0. I don't expect disks to be filtered out because of that.
  • I have not set up OMSA yet. These servers are fairly new (to us) and I was hoping to not have to do it for a while...

  1. Are you attempting to perform this configuration from the OMSA gui? Behavior like this sounds typical of problems occasionally seen in that software.

    Try configuring from the PERC BIOS menu during boot (Ctrl+R) - you'll likely have better success there.

    If you want to deal with the config bug itself, try using a different version of OMSA (either latest, or even a slightly older version if you're already up to date), and ensure your PERC firmware and driver are updated to the latest versions.

  2. If I were you, I would update the firmware from CD. You can download it from the Dell website, then CTRL + R and setup from there. After disks have been configured, I would install Windows Server and download latest firmware and driver for Windows and install the latest ones. I know sometimes CD package doesn't come with newest drivers or firmwares.
